Class TLcdXLinkExpressionFactory

java.lang.Object

com.luciad.format.xml.bind.xlink.TLcdXLinkExpressionFactory

All Implemented Interfaces:

ILcdXLinkExpressionFactory

public class TLcdXLinkExpressionFactory
extends Object
implements ILcdXLinkExpressionFactory

Implementation of ILcdXLinkExpressionFactory that is able to resolve references based on XML ID (i.e. hrefs like '#id') and xpointer expressions. In both cases, the linked elements have to be inside the document that is being decoded.

This class requires access to the TLcdXMLSchemaBasedMapping of the decoder. It expects the mapping to be available in the given ILcdXMLDocumentContext with key SCHEMA_BASED_MAPPING.

Since:

10.0

Method Details

compile

public ILcdXLinkExpression compile(TLcdXLinkSimpleLink aLink,
 ILcdXMLDocumentContext aContext)

Description copied from interface: ILcdXLinkExpressionFactory

Compiles a given href attribute into an ILcdXLinkExpression. This method is typically called during decoding when an xlink:href attribute is encountered.

If no expression can be created for the given href, null should be returned.

Specified by:

compile in interface ILcdXLinkExpressionFactory

Parameters:

aLink - the link for which an expression is to be created

aContext - the document context in which the href is to be evaluated

Returns:

an expression that can be evaluated to resolve the xlink
